-Binding for IDT VersaClock 5,6 programmable i2c clock generators.
-
-The IDT VersaClock 5 and VersaClock 6 are programmable i2c clock
-generators providing from 3 to 12 output clocks.
-
-==I2C device node==
-
-Required properties:
-- compatible: shall be one of
- "idt,5p49v5923"
- "idt,5p49v5925"
- "idt,5p49v5933"
- "idt,5p49v5935"
- "idt,5p49v6901"
- "idt,5p49v6965"
-- reg: i2c device address, shall be 0x68 or 0x6a.
-- #clock-cells: from common clock binding; shall be set to 1.
-- clocks: from common clock binding; list of parent clock handles,
- - 5p49v5923 and
- 5p49v5925 and
- 5p49v6901: (required) either or both of XTAL or CLKIN
- reference clock.
- - 5p49v5933 and
- - 5p49v5935: (optional) property not present (internal
- Xtal used) or CLKIN reference
- clock.
-- clock-names: from common clock binding; clock input names, can be
- - 5p49v5923 and
- 5p49v5925 and
- 5p49v6901: (required) either or both of "xin", "clkin".
- - 5p49v5933 and
- - 5p49v5935: (optional) property not present or "clkin".
-
-==Mapping between clock specifier and physical pins==
-
-When referencing the provided clock in the DT using phandle and
-clock specifier, the following mapping applies:
-
-5P49V5923:
- 0 -- OUT0_SEL_I2CB
- 1 -- OUT1
- 2 -- OUT2
-
-5P49V5933:
- 0 -- OUT0_SEL_I2CB
- 1 -- OUT1
- 2 -- OUT4
-
-5P49V5925 and
-5P49V5935:
- 0 -- OUT0_SEL_I2CB
- 1 -- OUT1
- 2 -- OUT2
- 3 -- OUT3
- 4 -- OUT4
-
-5P49V6901:
- 0 -- OUT0_SEL_I2CB
- 1 -- OUT1
- 2 -- OUT2
- 3 -- OUT3
- 4 -- OUT4
-
-==Example==

-/* 25MHz reference crystal */

- compatible = "fixed-clock";
- #clock-cells = <0>;
- clock-frequency = <25000000>;

-
- /* Connect XIN input to 25MHz reference */
- clocks = <&ref25m>;
- clock-names = "xin";
